dovecot - Apr 2013 - Problem with "convert" Plugin

Hello,

I got a Problem with the "convert" Plugin. Trying to convert from mbox
to maildir Format.
	OS: CentOS release 5.8 (Final)
	dovecot -version: 1.0.7 (Centos RPM)
	convert Plugin call: convert_mail = mbox:/opt/pop3/%u:INBOX=/var/spool/mail/%u

When converting to maildir - POP3 works fine (except the lost UIDL - so every
server-saved message is double downloaded - but did not find any fix for this
problem with convert plugin)
But the IMAP In-Boxes give me some headache .
All Folders are converted correct - and displayed in Mail Client. But all Mails
in the IMAP INBOX are "lost" (at least Mail Client won't show them
anymore)
Newly delivered Mails to the Inbox work - but all older ones are missing.

When looking into this Folder: /var/maildata/USER/Maildir/cur/ I can see that
newly delivered mails look like this:
	1366122898.14776_0.SERVERNAME:2,
And the old - converted ones like this:
	1366119758.P14442Q12M682874.SERVERNAME:2,


Can someone point me in the right direction why the converted Mails are missing?
(It worked on other Servers - about 1 year ago - without any problem?!)

Thank you

No idea, could be a bug in convert plugin. v1.0 is rather old.
